To @ZZ whom t may concern.-

Beit known that I, JOHN WILLIAM I-IULL, a citizen of the United States,residing at San Antonio, in the county of Bexar and State of Texas, haveinvented a new and useful Improvement in Closures for Bottles, &c., ofwhich the following is a speciiication.

My invention relates to an improvement in closures for bottles, itsobject being to produce a simple, cheap, and eiiicient closure which canreadily be applied to the bottle and which cannot be lremoved withoutevidence of such fact.

My invention consists in certain novel features of construction,arrangement, and combination of parts, as will be hereinafter fullydescribed, and pointed out in the claims.

In the drawings, Figure l is a vertical section oi a bottle-neck withthe stopper placed in position preparatory to expanding the same. Fig. 2is a similar view showing the stopper expanded and locked in position.Fig. 3 is an inverted plan view ofthe stopper. Fig. 4 is a sectionalview of another form of stopper. Fig. 5 is a similar view showing thisforni as applied to a bottle. Fig. 6 is a sectional view of another formof stopper, and Fig. 7 is a similar view showing this particular formapplied to a bottle.

In carrying out my invention I make the neck oi the bottle A with theinternal annular groove a, formed by the overhanging ledge a. The baseof said groove is iiat, and the overhanging ledge a does not extendinwardly to the vertical line of the Jface of the bore of thebottle-neck, leaving the space at the extreme yend of the bottle-neckgreater than the bore of the neck-that is the diameter of the opening atthe top is greater than that oi the bore oi the bottle-neck.

The stopper B is made of some soit expansible flexible metal-such aslead, aluminium, tin, &c.--in an inverted-cup shape, the side walls b ofsaid stopper diverging downwardly, as shown in Fig. 1.

The upper wall b of the stopper is provided with the rounded edge b3 andwith one or more slits b2, which are oi inverted-V shape, as shown inFigs. 1 and 2. These slits permit a small quantity of the liquid withinthe bottle to be discharged when the bottle having my improved closureis inverted. If desird, however, the slits may be entirely omitte Toapply my closure to the bottle after it has been Jfilled with thedesired liquid., all that is necessary is to place the stopper B withthe lower edge of the walls l) resting on the base of the groove a, thediameter of the bottom of the inverted-cup-shaped stopper being suchthat it just passes inside of the ledge 0/ of the bottle-neck. Pressureis now put upon the top of the stopper, which will cause the lower edgeof the stopper to spread and be crowded under the overhanging ledge aand lill the groove 0 thus forming a hermetic seal at the edges oi saidside walls, suiiicient pressure being put on the stopper to cause it tolit tightly under the shoulder a', so that any attempt to remove thestopper will result in its damage, so that it cannot be used a secondtime without evidence of that fact, particularly if an instrument beinserted in the slits for that purpose, as the bridge between such slitswhere more than ,one are used would be easily ruptured by an attempt topry open the stopper in that manner.

As shown in Fig. 4, I may Jform the stopper B4 with an annular bead orprojection b4 at its lower edge. To insert this form of stopper, a toolhaving a concave seat which just rits over the upper portion of thestopper is used. The lower edge of the tool resting on the top of theannular bead b4 is shown in dotted lines, Fig. 4. Now by Jforcing downthe tool the stopper will be iattened and the bead spread and crowdedinto the annular groove in the neck of the bottle.

As shown in Figs. 6 and 7, the stopper Bls may be formed of a thickenedupper portion, the lower end being flared outwardly or diverged andbrought to a thin edge o6. This form of stopper is also locked in thebottleneck by the same tool as used in placing the stopper shown in Fig.4, the lower edge b being spread and crowded into the annular groove aof the bottle-neck. The slits may be used in these forms or not, asdesired.

Owing to the ductility of the metals used and the different relativethickness of the edge and body of the stopper, the Stoppers IOO shouldernear its upper end and an annular internally-projecting ledge of greaterdiame- 1 ter than the bore of the bottle-neck, said ledge lying abovesaid shoulder, of a stopper composed of ileXible expansible metal of aninverted-cup-shape having outwardly-flared side Walls and provided withan annular bead 2 at its lower end.

JOHN WILLIAM HULL.
